How does the lateral displacement depend on the refractive index

Answer»

The lateral shift can be derived as:

X= l•sin(i-r)/cos(r) 

where l is the length of the glassslab.

Here you can see that lateral shift (x) depends on angle of refraction (r) also. And r is dependent on refractive index (n) i.e. r = asin( sin(i)/ n) (Snell's Law).

HENCE, lateral shift also depends on the refractive index of the glass SLAB.
